About the Book
I wanted to write the book I would have needed 5 years ago.
"By reading this book, you won’t just learn new techniques — you’ll transform the way you approach software development. You’ll gain clear, actionable steps to solve problems, communicate with unprecedented clarity, and estimate projects more accurately. In essence, you’ll be equipped to dismantle complexity and foster collaboration like never before." - Adam Dymitruk
"This is not just another technical book—it’s a roadmap to more predictable, maintainable, and successful software projects. Martin Dilger has created an invaluable resource that I believe will influence how we approach software development for years to come." - Gabriel. N. Schenker
"Apart from having unified so many spread resources into one single place of reference, I wanted to thank you especially for your WRITING STYLE. It's such a delight reading you. I've hardly ever experienced before the feeling of reading a best seller when reading a technical/business book. " - Jacobo Martin
"Focusing on a practical implementaion really worked for me. I appreciate the work you have done here." - Gary Craine
"Highly recommended reading" - Michael Plagge
"Thanks for writing the book, it will save me so much time and toil. I really like the Todo pattern to simplify the Saga. Also using an aggregate for uniqueness check is very nice." - William Power
"The book is packed with knowledge and provides concrete example implementations. It advances the entire topic and makes it easier for developers to access. I can only recommend it." - Sebastian Bortz
"The book is really great, practical, easy to read !" - Vincent Vermesh
"I just finished reading Part 1 of your book, and I’m thrilled. The book has truly captivated me—I can’t stop reading!" - Domenic Cassisi
"Got my (physical) copy as well here in the US! Thanks for all the hard work that went into this Martin. I started reading the digital version but now that I have a physical copy I look forward to reading it cover to cover and giving it the attention and focus it deserves. From what I've seen thus far I will be recommending this book as required reading for any team I work with going forward - your writing is clear, concise, and very easy to follow - it's been a joy to read and I look forward to having it as a reference that I can return to many times over as the journey continues!" - Matt Burton
"really enjoying the book! It has simplified event sourcing for me and how to put it into practice. " - T. Stuttart
"Your book is fantastic! I'm loving every page. It's now a must-read for all new hires I mentor."' - Murray McDonald
"You have no idea how much I am enjoying the book." - Leo Ephstein
This book gives a practical introduction to eventmodeling and eventsourcing with a focus on how to implement eventsourced systems in practice.
Unlike other books covering the topic, we will really dive into the code and build a softwaresystem basically from idea to running software using state of the art development practices.
BONUS - one new "missing chapter" added every 14 days
In Part I, we´ll cover the foundations of distributed systems. You will learn about CQRS, Eventsourcing and the fundamentals that took me 15 years to learn.
Part II focuses on the modelling part - I will show you how I model information systems using Eventmodeling in a practical way.
Part III really goes into the code - finally showing how an eventsourcing system is implemented.
Part IV builds a comprehensive Pattern Catalog and gives you quick guidance no how to implement typical scenarios in eventsourced systems.
There is an Online Course that follows the same structure as this book.
You can read and apply everything you learned directly.
